I have success to report:
I took another crack at trying to get my skeins the same color. I don't know why I couldn't just give up on it, but it just got personal, you know? The great thing about tenacity is that it always yields conclusion. Not necessarily the one you think you want, but there will be closure of some sort if you refuse to give up.
And no, the two groups are still not perfectly matched, but I have pronounced them close enough to fake it. I'll alternate rows or something when I knit it. And this is a way better color than it was to start with.
Lest you think that I have abandoned my KAL yarn fulfilment process to play with recycled sweaters; Fear Not - I give you the following News Flash:
If you live outside the United States, Your supplemental KAL yarn was mailed yesterday, via USPS.
If you live in the USA, in a state not located on the West Coast, your yarn will be mailed today.
If you live in the USA, in Oregon, Washington or California, Your yarn will be mailed tomorrow.
And if you picked up your yarn personally at Knit Night here in Portland, see me tonight - I'll bring the string!
Thank you for hanging in there with me, my knitalong friends - perseverance shall prevail!
